We still need to decide how to handle non-specfic `chainId` in the JSON
encoding of authorizations. With `chainId` being a uint64, the previous
implementation just used value zero. However, it might actually be more
correct to use the value `null` for this case.
This pull request refactors the genesis setup function, the major
changes are highlighted here:
**(a) Triedb is opened in verkle mode if `EnableVerkleAtGenesis` is
configured in chainConfig or the database has been initialized previously with
`EnableVerkleAtGenesis` configured**.
A new config field `EnableVerkleAtGenesis` has been added in the
chainConfig. This field must be configured with True if Geth wants to initialize
the genesis in Verkle mode.
In the verkle devnet-7, the verkle transition is activated at genesis.
Therefore, the verkle rules should be used since the genesis. In production
networks (mainnet and public testnets), verkle activation always occurs after
the genesis block. Therefore, this flag is only made for devnet and should be
deprecated later. Besides, verkle transition at non-genesis block hasn't been
implemented yet, it should be done in the following PRs.
**(b) The genesis initialization condition has been simplified**
There is a special mode supported by the Geth is that: Geth can be
initialized with an existing chain segment, which can fasten the node sync
process by retaining the chain freezer folder.
Originally, if the triedb is regarded as uninitialized and the genesis block can
be found in the chain freezer, the genesis block along with genesis state will be
committed. This condition has been simplified to checking the presence of chain
config in key-value store. The existence of chain config can represent the genesis
has been committed.
- it was failing because the maximum data length (previously `dataSize`)
was set to `txMaxSize - 213` but should had been `txMaxSize - 103` and
the last call `dataSize+1+uint64(rand.Intn(10*txMaxSize)))` would
sometimes fail depending on rand.Intn.
- Maximal transaction data size comment (invalid) replaced by code logic
to find the maximum tx length without its data length
- comments and variable naming improved for clarity
- 3rd pool add test replaced to add just 1 above the maximum length,
which is important to ensure the logic is correct

As the node hash scheme in verkle and merkle are totally different, the
original default node hasher in pathdb is no longer suitable. Therefore,
this pull request configures different node hasher respectively.
This change fixes is a rare bug in test generator: If the run is very unlucky it
can use `modifyAccountOp` / `deleteAccountOp` without creating any
account, leading to have a trie root same as the parent.
This change makes the first operation always be a creation.
This commit makes it so that the struct logger will not emit logs while
system calls are being executed. This will make it consistent with
the JSON and MD loggers. It is as it stands hard to distinguish when
system calls are being processed vs when a tx is being processed.

Here I am proposing two small changes to the exported API for EIP-7702:
(1) `Authorization` has a very generic name, but it is in fact only used
for one niche use case: authorizing code in a `SetCodeTx`. So I propose
calling it `SetCodeAuthorization` instead. The signing function is
renamed to `SignSetCode` instead of `SignAuth`.
(2) The signing function for authorizations should take key as the first
parameter, and the authorization second. The key will almost always be
in a variable, while the authorization can be given as a literal.
This fixes a regression introduced recently. Without this fix, it's not
possible to use statetests without `.json` suffix. This is problematic for
goevmlab `minimizer`, which appends the suffix `.min` during processing.
Fixing some issues I found while regenerating RPC tests for Prague:
- Authorization signature values were not encoded as hex
- `requestsRoot` in block should be `requestsHash`
- `authorizationList` should work for `eth_call`
Noticed this omission while doing some work on goevmlab. We don't
properly type some of the opcodes, but apparently implicit casting works
in all the internal usecases.
Adding some missing functionality I noticed while updating the hivechain
tool for the Prague fork:
- we forgot to process the parent block hash
- added `ConsensusLayerRequests` to get the requests list of the block
This change adds methods which makes it possible for to wait for a transaction with a specific hash when deploying contracts during abi bind interaction.

In this pull request, the state iterator is implemented. It's mostly a copy-paste
from the original state snapshot package, but still has some important changes
to highlight here:
(a) The iterator for the disk layer consists of a diff iterator and a disk iterator.
Originally, the disk layer in the state snapshot was a wrapper around the disk,
and its corresponding iterator was also a wrapper around the disk iterator.
However, due to structural differences, the disk layer iterator is divided into
two parts:
- The disk iterator, which traverses the content stored on disk.
- The diff iterator, which traverses the aggregated state buffer.
Checkout `BinaryIterator` and `FastIterator` for more details.
(b) The staleness management is improved in the diffAccountIterator and
diffStorageIterator
Originally, in the `diffAccountIterator`, the layer’s staleness had to be checked
within the Next function to ensure the iterator remained usable. Additionally,
a read lock on the associated diff layer was required to first retrieve the account
blob. This read lock protection is essential to prevent concurrent map read/write.
Afterward, a staleness check was performed to ensure the retrieved data was
not outdated.
The entire logic can be simplified as follows: a loadAccount callback is provided
to retrieve account data. If the corresponding state is immutable (e.g., diff layers
in the path database), the staleness check can be skipped, and a single account
data retrieval is sufficient. However, if the corresponding state is mutable (e.g.,
the disk layer in the path database), the callback can operate as follows:
```go
func(hash common.Hash) ([]byte, error) {
dl.lock.RLock()
defer dl.lock.RUnlock()
if dl.stale {
return nil, errSnapshotStale
}
return dl.buffer.states.mustAccount(hash)
}
```
The callback solution can eliminate the complexity for managing
concurrency with the read lock for atomic operation.
This PR implements EIP-7702: "Set EOA account code".
Specification: https://eips.ethereum.org/EIPS/eip-7702
> Add a new transaction type that adds a list of `[chain_id, address,
nonce, y_parity, r, s]` authorization tuples. For each tuple, write a
delegation designator `(0xef0100 ++ address)` to the signing account’s
code. All code reading operations must load the code pointed to by the
designator.

Closes#23210
# Context
When deploying Geth in Kubernetes with ReplicaSets, we encountered two
DNS-related issues affecting node connectivity. First, during startup,
Geth tries to resolve DNS names for static nodes too early in the config
unmarshaling phase. If peer nodes aren't ready yet (which is common in
Kubernetes rolling deployments), this causes an immediate failure:
```
INFO [11-26|10:03:42.816] Starting Geth on Ethereum mainnet...
INFO [11-26|10:03:42.817] Bumping default cache on mainnet provided=1024 updated=4096
Fatal: config.toml, line 81: (p2p.Config.StaticNodes) lookup idontexist.geth.node: no such host
```
The second issue comes up when pods get rescheduled to different nodes -
their IPs change but peers keep using the initially resolved IP, never
updating the DNS mapping.
This PR adds proper DNS support for enode:// URLs by deferring resolution
to connection time. It also handles DNS failures gracefully instead of failing
fatally during startup, making it work better in container environments where
IPs are dynamic and peers come and go during rollouts.

This PR modifies how the metrics library handles `Enabled`: previously,
the package `init` decided whether to serve real metrics or just
dummy-types.
This has several drawbacks:
- During pkg init, we need to determine whether metrics are enabled or
not. So we first hacked in a check if certain geth-specific
commandline-flags were enabled. Then we added a similar check for
geth-env-vars. Then we almost added a very elaborate check for
toml-config-file, plus toml parsing.
- Using "real" types and dummy types interchangeably means that
everything is hidden behind interfaces. This has a performance penalty,
and also it just adds a lot of code.
This PR removes the interface stuff, uses concrete types, and allows for
the setting of Enabled to happen later. It is still assumed that
`metrics.Enable()` is invoked early on.
The somewhat 'heavy' operations, such as ticking meters and exp-decay,
now checks the enable-flag to prevent resource leak.
The change may be large, but it's mostly pretty trivial, and from the
last time I gutted the metrics, I ensured that we have fairly good test
coverage.

changes to evm flag handling.
This PR mainly focuses on `evm run` subcommand, to use the same flags

It's a pull request based on https://github.com/ethereum/go-ethereum/pull/30643
In this pull request, the partial functional state reader is enabled if **legacy snapshot
is not enabled**. The tracked flat states in pathdb will be used to serve the state
retrievals, as the second implementation to fasten the state access.
This pull request should be a noop change in normal cases.
This PR extends the Hooks interface with a new method,
`OnSystemCallStartV2`, which takes `VMContext` as its parameter.
Motivation
By including `VMContext` as a parameter, the `OnSystemCallStartV2` hook
achieves parity with the `OnTxStart` hook in terms of provided insights.
This alignment simplifies the inner tracer logic, enabling consistent
handling of state changes and internal calls within the same framework.

This PR refactors the structlog a bit, making it so that it can be used
in a streaming mode.
-------------
OBS: this PR makes a change in the input `config` config, the third
input-parem field to `debug.traceCall`. Previously, seteting it to e.g.
` {"enableMemory": true, "limit": 1024}` would mean that the response
was limited to `1024` items. Since an 'item' may include both memory and
storage, the actual size of the response was undertermined.
After this change, the response will be limited to `1024` __`bytes`__
(or thereabouts).
-----------
The commandline usage of structlog now uses the streaming mode, leaving
the non-streaming mode of operation for the eth_Call.
There are two benefits of streaming mode
1. Not have to maintain a long list of operations,
2. Not have to duplicate / n-plicate data, e.g. memory / stack /
returndata so that each entry has their own private slice.

Lots of packages depend on eth/downloader just for the SyncMode type.
Since we have a dedicated package for eth protocol configuration, it
makes more sense to define SyncMode there, turning eth/downloader into
more of a leaf package.
This flag is very rarely needed, so it's OK for it to have a verbose
name. The name --trace also conflicts with the concept of EVM tracing,
which is much more heavily used.
The fuzzer added recenly to fuzz the eth handler doesn't
build on oss-fuzz, because it also has dependencies in the peer_test.go.
This change fixes it, I hope, by adding that file also for preprocessing.
* unify `staterunner` and `blockrunner` CLI flags, especially around
tracing
* added support for struct logger or json logging (although having issue
#30658)
* new --cross-check flag to validate the stateless witness collection
/ execution matches stateful
* adds support for tracing the stateless execution when a tracer is set
(to more easily debug differences)
* --human for more readable test summary
* directory or file input, so if you pass tests/spec-tests/fixtures/blockchain_tests it will execute all
blockchain tests

This PR introduces a `ContractCodeReader` interface with functions defined:
type ContractCodeReader interface {
Code(addr common.Address, codeHash common.Hash) ([]byte, error)
CodeSize(addr common.Address, codeHash common.Hash) (int, error)
}
This interface can be implemented in various ways. Although the codebase
currently includes only one implementation, additional implementations
could be created for different purposes and scenarios, such as a code
reader designed for the Verkle tree approach or one that reads code from
the witness.
*Notably, this interface modifies the function’s semantics. If the
contract code is not found, no error will be returned. An error should
only be returned in the event of an unexpected issue, primarily for
future implementations.*
The original state.Reader interface is extended with ContractCodeReader
methods, it gives us more flexibility to manipulate the reader with additional
logic on top, e.g. Hooks.
type Reader interface {
ContractCodeReader
StateReader
}

This pull request ports some changes from the main state snapshot
integration one, specifically introducing the flat state tracking in
pathdb.
Note, the tracked flat state changes are only held in memory and won't
be persisted in the disk. Meanwhile, the correspoding state retrieval in
persistent state is also not supported yet. The states management in
disk is more complicated and will be implemented in a separate pull
request.
Part 1: https://github.com/ethereum/go-ethereum/pull/30752
The existing implementation is correct when building and verifying
blocks, since we will only collect non-empty requests into the block
requests list.
But it isn't correct for cases where a requests list containing empty
items is sent by the consensus layer on the engine API. We want to
ensure that empty requests do not cause a difference in validation
there, so the commitment computation should explicitly skip them.
Since we don't really support custom networks anymore, we don't need the
bootnode utility. In case a discovery-only node is wanted, it can still be run using cmd/devp2p.
This workaround is meant to minimize the possibility for snapshot generation
once the geth node upgrades to new version (specifically #30752 )
In #30752, the journal format in state snapshot is modified by removing
the destruct set. Therefore, the existing old format (version = 0) will be
discarded and all in-memory layers will be lost. Unfortunately, the lost
in-memory layers can't be recovered by some other approaches, and the
entire state snapshot will be regenerated (it will last about 2.5 hours).
This pull request introduces a workaround to adopt the legacy journal if
the destruct set contained is empty. Since self-destruction has been
deprecated following the cancun fork, the destruct set is expected to be nil for
layers above the fork block. However, an exception occurs during contract
deployment: pre-funded accounts may self-destruct, causing accounts with
non-zero balances to be removed from the state. For example,
https://etherscan.io/tx/0xa087333d83f0cd63b96bdafb686462e1622ce25f40bd499e03efb1051f31fe49).
For nodes with a fully synced state, the legacy journal is likely compatible with
the updated definition, eliminating the need for regeneration. Unfortunately,
nodes performing a full sync of historical chain segments or encountering
pre-funded account deletions may face incompatibilities, leading to automatic
snapshot regeneration.
Reusing state between benchmark iterations resulted in inconsistent
results across runs, which surfaced in https://github.com/ethereum/go-ethereum/issues/30778 .
If these errors are triggered again, they will now trigger panic.

This reverts commit 23800122b3.

```

Before the original PR, the snapshot would block the function until the
disk layer
was fully generated under the following conditions:
(a) explicitly required by users with `AsyncBuild = false`.
(b) the snapshot was being fully rebuilt or *the disk layer generation
had resumed*.
Unfortunately, with the changes introduced in that PR, the snapshot no
longer waits
for disk layer generation to complete if the generation is resumed. It
brings lots of
uncertainty and breaks this tiny debug feature.
This updates the message you get when trying to initialize Geth with
genesis.json that doesn't have `terminalTotalDifficulty`. The previous
message was a bit obscure, I had to check the code to find out what the
problem was.
This PR is purely for improved readability; I was doing work involving
the file and think this may help others who are trying to understand
what's going on.
1. `snapshot.Tree.Rebuild()` now returns a function that blocks until
regeneration is complete, allowing `Tree.waitBuild()` to be removed
entirely as all it did was search for the `done` channel behind this new
function.
2. Its usage inside `New()` is also simplified by (a) only waiting if
`!AsyncBuild`; and (b) avoiding the double negative of `if !NoBuild`.

#28764 updated `func MakeTopics` to support negative `*big.Int`s.
However, it also changed the behavior of the function from just
_reading_ the input `*big.Int` via `Bytes()`, to leveraging
`big.U256Bytes` which is documented as being _destructive_:
This change updates `MakeTopics` to not mutate the original, and
also applies the same change in signer/core/apitypes.
This PR improves the output of the markdown logger a bit.
- Remove `RStack` field,
- Move `Stack` last, since it may have very large vertical expansion
- Make the pre- and post-exec metadata structured into a bullet-list
This change fixes a bug on the `DirectoryFlag` and the `BigFlag`, which would trigger a `panic` with the message "flag redefined" in case an alias was added to such a flag.
This pull request removes the destruct flag from the state snapshot to
simplify the code.
Previously, this flag indicated that an account was removed during a
state transition, making all associated storage slots inaccessible.
Because storage deletion can involve a large number of slots, the actual
deletion is deferred until the end of the process, where it is handled
in batches.
With the deprecation of self-destruct in the Cancun fork, storage
deletions are no longer expected. Historically, the largest storage
deletion event in Ethereum was around 15 megabytes—manageable in memory.
In this pull request, the single destruct flag is replaced by a set of
deletion markers for individual storage slots. Each deleted storage slot
will now appear in the Storage set with a nil value.
This change will simplify a lot logics, such as storage accessing,
storage flushing, storage iteration and so on.
This pull request refactors the EVM constructor by removing the
TxContext parameter.
The EVM object is frequently overused. Ideally, only a single EVM
instance should be created and reused throughout the entire state
transition of a block, with the transaction context switched as needed
by calling evm.SetTxContext.
Unfortunately, in some parts of the code, the EVM object is repeatedly
created, resulting in unnecessary complexity. This pull request is the
first step towards gradually improving and simplifying this setup.

In many cases, there is a need to create somewhat nontrivial bytecode. A
recent example is the verkle statetests, where we want a `CREATE2`- op
to create a contract, which can then be invoked, and when invoked does a
selfdestruct-to-self.
It is overkill to go full solidity, but it is also a bit tricky do
assemble this by concatenating bytes. This PR takes an approach that
has been used in in goevmlab for several years.
Using this utility, the case can be expressed as:
```golang
// Some runtime code
runtime := program.New().Ops(vm.ADDRESS, vm.SELFDESTRUCT).Bytecode()
// A constructor returning the runtime code
initcode := program.New().ReturnData(runtime).Bytecode()
// A factory invoking the constructor
outer := program.New().Create2AndCall(initcode, nil).Bytecode()
```
We have a lot of places in the codebase where we concatenate bytes, cast
from `vm.OpCode` . By taking tihs approach instead, thos places can be made a
bit more maintainable/robust.
This adds an API method `DropTransactions` to legacy pool, blob pool and
txpool interface. This method removes all txs currently tracked in the
pools.
It modifies the simulated beacon to use the new method in `Rollback`
which removes previous hacky implementation that also erroneously reset
the gas tip to 1 gwei.

The [kilic](https://github.com/kilic/bls12-381) bls12381 implementation
has been archived. It shouldn't be necessary to include it as a fuzzing
target any longer.
This also adds fuzzers for G1/G2 mul that use inputs that are guaranteed
to be valid. Previously, we just did random input fuzzing for these
precompiles.
This is one further step towards removing account management from
`geth`. This PR deprecates the flag `unlock`, and makes the flag moot:
unlock via geth is no longer possible.
This change invokes the OnCodeChange hook when selfdestruct operation is performed, and a contract is removed. This is an event which can be consumed by tracers.
This PR moves chain config related code (config file processing, fork
logic, network defaults) from `beacon/types` and `beacon/blsync` into
`beacon/params` while the command line flag logic of the chain config is
moved into `cmd/utils`, thereby removing the cli dependencies from
package `beacon` and its sub-packages.
When `evm statetest --bench` is specified, benchmark the execution
similarly to `evm run`.
Also adds the ability to filter tests by name, index and fork.

- [x] reduce mem overhead in the setup-phase of some tests
- [x] Marks some tests with a long setup-phase to be skipped if `-short`

This test depends on a 100ms timer, which fails quite often, messing up
our pipelines. Hook directly into the internal version of getPayload
which has the capacity to wait for the full payload before returning.
This might not be absolutely correct from a test perspective, but it
beats failing ci. The alternative would be to expose the full build hook
into the outside, but it might be a bit overkill for this scenario.
This PR is a first step towards removing account management from geth,
and contains a lot of the user-facing changes.
With this PR, the `personal` namespace disappears. **Note**: `personal`
namespace has been deprecated for quite some time (since
https://github.com/ethereum/go-ethereum/pull/26390 1 year and 8 months
ago), and users who have wanted to use it has been forced to used the
flag `--rpc.enabledeprecatedpersonal`. So I think it's fairly
non-controversial to drop it at this point.
Specifically, this means:
- Account/wallet listing
-`personal.getListAccounts`
-`personal.listAccounts`
-`personal.getListWallets`
-`personal.listWallets`
- Lock/unlock
-`personal.lockAccount`
-`personal.openWallet`
-`personal.unlockAccount`
- Sign ops
-`personal.sign`
-`personal.sendTransaction`
-`personal.signTransaction`
- Imports / inits
-`personal.deriveAccount`
-`personal.importRawKey`
-`personal.initializeWallet`
-`personal.newAccount`
-`personal.unpair`
- Other:
-`personal.ecRecover`
The underlying keystores and account managent code is still in place,
which means that `geth --dev` still works as expected, so that e.g. the
example below still works:
```
> eth.sendTransaction({data:"0x6060", value: 1, from:eth.accounts[0]})
```
Also, `ethkey` and `clef` are untouched.
With the removal of `personal`, as far as I know we have no more API
methods which contain credentials, and if we want to implement
logging-capabilities of RPC ingress payload, it would be possible after
this.

Currently we have a custom TextMarshalerFlag. It's a nice idea, allowing
anything implementing text marshaller to be used as a flag. That said,
we only ever used it in one place because it's not that obvious how to
use and it needs some boilerplate on the type itself too, apart of the
heavy boilerplate got the custom flag.
All in all there's no *need* to drop this feature just now, but while
porting the cmds over to cli @v3, all other custom flags worker
perfectly, whereas this one started crashing deep inside the cli
package. The flag handling in v3 got rebuild on generics and there are a
number of new methods needed; and my guess is that maybe one of them
doesn't work like this flag currently is designed too.
We could definitely try and redesign this flag for cli v3... but all
that effort and boilerplate just to use it for 1 flag in 1 location,
seems not worth it. So for now I'm suggesting removing it and maybe
reconsider a similar feature in cli v3 with however it will work.
I think the core code should generally be agnostic about the witness and
the statedb layer should determine what elements need to be included in
the witness. Because code is accessed via `GetCode`, and
`GetCodeLength`, the statedb will always know when it needs to add that
code into the witness.
The edge case is block hashes, so we continue to add them manually in
the implementation of `BLOCKHASH`.
It probably makes sense to refactor statedb so we have a wrapped
implementation that accumulates the witness, but this is a simpler
change that makes #30078 less aggressive.
Looking at the cpu profile of a burntpix benchmark, I noticed that a lot
of time was spent in gas-used, in the interpreter loop. It's an actual
call (not inlined), which explicitly wants to be ignored by tracing
("tracing.GasChangeIgnored"), so it can be safely and simply inlined.
The other change is in `pushX`. These also do a call to
`common.RightPadBytes`. I replaced that by a doing a corresponding `Lsh`
on the `u256` if needed. Note: it's needed only to make the stack output
look right, for fuzzers. It technically doesn't matter what we put
there: if code ends on a pushdata immediate, nothing will consume the
stack element. We could just as well just ignore it, if we didn't care
about fuzzers (which I do).
Seems quite a lot faster on burntpix, according to my runs.

When using the prestateTracer, in some cases users are only concerned
with balances or nonce information, and are not interested in the lengthy
contract code or storage data.
Therefore, this PR introduces two new configuration options in the
`prestateTracerConfig` structure:
- `disableCode`
- `disableStorage`
These options allow users to control whether the tracer returns contract
code and storage data during execution tracing. By setting these
options, users can more flexibly customize their needs and focus on
obtaining information that is more critical and relevant to their
specific use cases.
These options work with the default mode as well as `diffMode: true`.

This PR adds `DeleteRange` to `ethdb.KeyValueWriter`. While range
deletion using an iterator can be really slow, `DeleteRange` is natively
supported by pebble and apparently runs in O(1) time (typically 20-30ms
in my tests for removing hundreds of millions of keys and gigabytes of
data). For leveldb and memorydb an iterator based fallback is
implemented. Note that since the iterator method can be slow and a
database function should not unexpectedly block for a very long time,
the number of deleted keys is limited at 10000 which should ensure that
it does not block for more than a second. ErrTooManyKeys is returned if
the range has only been partially deleted. In this case the caller can
repeat the call until it finally succeeds.

This PR moves the logging/tracing-facilities out of `*state.StateDB`,
in to a wrapping struct which implements `vm.StateDB` instead.
In most places, it is a pretty straight-forward change:
- First, hoisting the invocations from state objects up to the statedb.
- Then making the mutation-methods simply return the previous value, so
that the external logging layer could log everything.
Some internal code uses the direct object-accessors to mutate the state,
particularly in testing and in setting up state overrides, which means
that these changes are unobservable for the hooked layer. Thus, configuring
the overrides are not necessarily part of the API we want to publish.
The trickiest part about the layering is that when the selfdestructs are
finally deleted during `Finalise`, there's the possibility that someone
sent some ether to it, which is burnt at that point, and thus needs to
be logged. The hooked layer reaches into the inner layer to figure out
these events.
In package `vm`, the conversion from `state.StateDB + hooks` into a
hooked `vm.StateDB` is performed where needed.

Way back we've added `common.math.BigMin` and `common.math.BigMax`.
These were kind of cute helpers, but unfortunate ones, because package
all over out codebase added dependencies to this package just to avoid
having to write out 3 lines of code.
Because of this, we've also started having package name clashes with the
stdlib `math`, which got solves even more badly by moving some helpers
over ***from*** the stdlib into our custom lib (e.g. MaxUint64). The
latter ones were nuked out in a previous PR and this PR nukes out BigMin
and BigMax, inlining them at all call sites.
As we're transitioning to uint256, if need be, we can add a min and max
to that.
Clique currently depends on the `accounts` package. This was a bit of a
big cannon even in the past, just to pass a signer "account" to the
Clique block producer. Either way, nowadays Geth does not support clique
mining any more, so by removing that bit of functionality from our code,
we can also break this dependency.
Clique should ideally be further torn out, but this at least gets us one
step closer to cleanups.
While looking at some mem profiles from `evm` runs, I noticed that
`goja` compilation of the bigint library was present. The bigint library
compilation happens in a package `init`, whenever the package
`eth/tracers/js` is loaded. This PR changes it to load lazily when
needed.
It becomes slightly faster with this change, and slightly less alloc:y.
Non-scientific benchmark with 100 executions:
```
time for i in {1..100}; do ./evm --code 6040 run; done;
```

```

Fixes an issue missed in #30576 where we send empty requests for a full
payload being resolved, causing hash mismatch later on when we get the
payload back via `NewPayload`.
Breaking changes:
- The ChainConfig was exposed to tracers via VMContext passed in
`OnTxStart`. This is unnecessary specially looking through the lens of
live tracers as chain config remains the same throughout the lifetime of
the program. It was there so that native API-invoked tracers could
access it. So instead we moved it to the constructor of API tracers.
Non-breaking:
- Change the default config of the tracers to be `{}` instead of nil.
This way an extra nil check can be avoided.
Refactoring:
- Rename `supply` struct to `supplyTracer`.
- Un-export some hook definitions.
~~Opening this as a draft to have a discussion.~~ Pressed the wrong
button
I had [a previous PR
](https://github.com/ethereum/go-ethereum/pull/24616)a long time ago
which reduced the peak memory used during reorgs by not accumulating all
transactions and logs.
This PR reduces the peak memory further by not storing the blocks in
memory.
However this means we need to pull the blocks back up from storage
multiple times during the reorg.
I collected the following numbers on peak memory usage:
// Master: BenchmarkReorg-8 10000 899591 ns/op 820154 B/op 1440
allocs/op 1549443072 bytes of heap used
// WithoutOldChain: BenchmarkReorg-8 10000 1147281 ns/op 943163 B/op
1564 allocs/op 1163870208 bytes of heap used
// WithoutNewChain: BenchmarkReorg-8 10000 1018922 ns/op 943580 B/op
1564 allocs/op 1171890176 bytes of heap used
Each block contains a transaction with ~50k bytes and we're doing a 10k
block reorg, so the chain should be ~500MB in size

## Description
Omit null `witness` field from payload envelope.
## Motivation
Currently, JSON encoded payload types always include `"witness": null`,
which, I believe, is not intentional.
calculating a reasonable tx blob fee cap (`max_blob_fee_per_gas *
total_blob_gas`) only depends on the excess blob gas of the parent
header. The parent header is assumed to be correct, so the method should
not be able to fail and return an error.
This change brings geth into compliance with the current engine API
specification for the Prague fork. I have moved the assignment of
ExecutionPayloadEnvelope.Requests into BlockToExecutableData to ensure
there is a single place where the type is removed.
While doing so, I noticed that handling of requests in the miner was not
quite correct for the empty payload. It would return `nil` requests for
the empty payload even for blocks after the Prague fork. To fix this, I
have added the emptyRequests field in miner.Payload.
Changelog: https://golangci-lint.run/product/changelog/#1610
Removes `exportloopref` (no longer needed), replaces it with
`copyloopvar` which is basically the opposite.
Also adds:
- `durationcheck`
- `gocheckcompilerdirectives`
- `reassign`
- `mirror`
- `tenv`

A couple of tests set the debug level to `TRACE` on stdout,
and all subsequent tests in the same package are also affected
by that, resulting in outputs of tens of megabytes.
This PR removes such calls from two packages where it was prevalent.
This makes getting a summary of failing tests simpler, and possibly
reduces some strain from the CI pipeline.
This implements recent changes to EIP-7685, EIP-6110, and

EOF-work. More recently, the code has been picked up and reworked for the new EOF
specification, by @MariusVanDerWijden , in https://github.com/ethereum/go-ethereum/pull/29518, and also @shemnon has contributed with fixes.
This PR is an attempt to start eating the elephant one small bite at a
time, by selecting only the eof-validation as a standalone piece which
can be merged without interfering too much in the core stuff.
In this PR:
- [x] Validation of eof containers, lifted from #29518, along with
test-vectors from consensus-tests and fuzzing, to ensure that the move
did not lose any functionality.
- [x] Definition of eof opcodes, which is a prerequisite for validation
- [x] Addition of `undefined` to a jumptable entry item. I'm not
super-happy with this, but for the moment it seems the least invasive
way to do it. A better way might be to go back and allowing nil-items or
nil execute-functions to denote "undefined".

This pull request removes the `fsync` of index files in freezer.ModifyAncients function for
performance gain.
Originally, fsync is added after each freezer write operation to ensure
the written data is truly transferred into disk. Unfortunately, it turns
out `fsync` can be relatively slow, especially on
macOS (see https://github.com/ethereum/go-ethereum/issues/28754 for more
information).
In this pull request, fsync for index file is removed as it turns out
index file can be recovered even after a unclean shutdown. But fsync for data file is still kept, as
we have no meaningful way to validate the data correctness after unclean shutdown.
---
**But why do we need the `fsync` in the first place?**
As it's necessary for freezer to survive/recover after the machine crash
(e.g. power failure).
In linux, whenever the file write is performed, the file metadata update
and data update are
not necessarily performed at the same time. Typically, the metadata will
be flushed/journalled
ahead of the file data. Therefore, we make the pessimistic assumption
that the file is first
extended with invalid "garbage" data (normally zero bytes) and that
afterwards the correct
data replaces the garbage.
We have observed that the index file of the freezer often contain
garbage entry with zero value
(filenumber = 0, offset = 0) after a machine power failure. It proves
that the index file is extended
without the data being flushed. And this corruption can destroy the
whole freezer data eventually.
Performing fsync after each write operation can reduce the time window
for data to be transferred
to the disk and ensure the correctness of the data in the disk to the
greatest extent.
---
**How can we maintain this guarantee without relying on fsync?**
Because the items in the index file are strictly in order, we can
leverage this characteristic to
detect the corruption and truncate them when freezer is opened.
Specifically these validation
rules are performed for each index file:
For two consecutive index items:
- If their file numbers are the same, then the offset of the latter one
MUST not be less than that of the former.
- If the file number of the latter one is equal to that of the former
plus one, then the offset of the latter one MUST not be 0.
- If their file numbers are not equal, and the latter's file number is
not equal to the former plus 1, the latter one is valid
And also, for the first non-head item, it must refer to the earliest
data file, or the next file if the
earliest file is not sufficient to place the first item(very special
case, only theoretical possible
in tests)
With these validation rules, we can detect the invalid item in index
file with greatest possibility.
---
But unfortunately, these scenarios are not covered and could still lead
to a freezer corruption if it occurs:
**All items in index file are in zero value**
It's impossible to distinguish if they are truly zero (e.g. all the data
entries maintained in freezer
are zero size) or just the garbage left by OS. In this case, these index
items will be kept by truncating
the entire data file, namely the freezer is corrupted.
However, we can consider that the probability of this situation
occurring is quite low, and even
if it occurs, the freezer can be considered to be close to an empty
state. Rerun the state sync
should be acceptable.
**Index file is integral while relative data file is corrupted**
It might be possible the data file is corrupted whose file size is
extended correctly with garbage
filled (e.g. zero bytes). In this case, it's impossible to detect the
corruption by index validation.
We can either choose to `fsync` the data file, or blindly believe that
if index file is integral then
the data file could be integral with very high chance. In this pull
request, the first option is taken.
Reverts ethereum/go-ethereum#30495
You are free to create a proper Clear method if that's the best way. But
one that does a proper cleanup, not some hacky call to set gas which
screws up logs, metrics and everything along the way. Also doesn't work
for legacy pool local transactions.
The current code had a hack in the simulated code, now we have a hack in
live txpooling code. No, that's not acceptable. I want the live code to
be proper, meaningful API, meaningful comments, meaningful
implementation.
Here we move the method that drops all transactions by temporarily increasing the fee
into the TxPool itself. It's better to have it there because we can set it back to the
configured value afterwards. This resolves a TODO in the simulated backend.
This PR fixes two tests, which had a tendency to sometimes write to the `*testing.T` `log` facility after the test function had completed, which is not allowed. This PR fixes it by using waitgroups to ensure that the handler/logwriter terminates before the test exits.
closes#30505
Extends the opcontext interface to include accessor for code being executed in current context. While it is possible to get the code via `statedb.GetCode`, that approach doesn't work for initcode.
In #27720, we introduced RPC global gas cap. A value of `0` means an unlimited gas cap. However, this was not the case for simulated calls. This PR fixes the behaviour.
This pull request skips the state snapshot update if the base layer is
not existent, eliminating the numerous warning logs after an unclean
shutdown.
Specifically, Geth will rewind its chain head to a historical block
after unclean shutdown and state snapshot will be remained as unchanged
waiting for recovery. During this period of time, the snapshot is unusable
and all state updates should be ignored/skipped for state snapshot update.
This is a work-around for a strange issue with travis, specifically,
`os=osx, go: 1.23.1`. When this is used, the actual go that ends up
being used is `go1.19.4 darwin/amd64 `.
Using `which go`, it told me that the `go` in the path was a softlink at
`/Users/travis/gopath/bin/go1.23.1 `. However, this was not true: using
`command -v go`, it told me that the actual `go` that was used is a
softlink at `/usr/local/bin/go`.
This change rewrites the `/usr/local/bin/go` softlink to point to the
binary at `/Users/travis/gopath/bin/go1.23.1`, so we get the right
go-version.
This PR integrates witness-enabled block production, witness-creating
payload execution and stateless cross-validation into the `engine` API.
The purpose of the PR is to enable the following use-cases (for API
details, please see next section):
- Cross validating locally created blocks:
- Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to
trigger witness creation too.
- Call `getPayload` as before to retrieve the new block and also the
above created witness.
- Call `executeStatelessPayload` against another client to
cross-validate the block.
- Cross validating locally processed blocks:
- Call `newPayloadWithWitness` instead of `newPayload` to trigger
witness creation too.
- Call `executeStatelessPayload` against another client to
cross-validate the block.
- Block production for stateless clients (local or MEV builders):
- Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to
trigger witness creation too.
- Call `getPayload` as before to retrieve the new block and also the
above created witness.
- Propagate witnesses across the consensus libp2p network for stateless
Ethereum.
- Stateless validator validation:
- Call `executeStatelessPayload` with the propagated witness to
statelessly validate the block.
*Note, the various `WithWitness` methods could also *just be* an
additional boolean flag on the base methods, but this PR wanted to keep
the methods separate until a final consensus is reached on how to
integrate in production.*
---
The following `engine` API types are introduced:
```go
// StatelessPayloadStatusV1 is the result of a stateless payload execution.
type StatelessPayloadStatusV1 struct {
Status string `json:"status"`
StateRoot common.Hash `json:"stateRoot"`
ReceiptsRoot common.Hash `json:"receiptsRoot"`
ValidationError *string `json:"validationError"`
}
```
- Add `forkchoiceUpdatedWithWitnessV1,2,3` with same params and returns
as `forkchoiceUpdatedV1,2,3`, but triggering a stateless witness
building if block production is requested.
- Extend `getPayloadV2,3` to return `executionPayloadEnvelope` with an
additional `witness` field of type `bytes` iff created via
`forkchoiceUpdatedWithWitnessV2,3`.
- Add `newPayloadWithWitnessV1,2,3,4` with same params and returns as
`newPayloadV1,2,3,4`, but triggering a stateless witness creation during
payload execution to allow cross validating it.
- Extend `payloadStatusV1` with a `witness` field of type `bytes` if
returned by `newPayloadWithWitnessV1,2,3,4`.
- Add `executeStatelessPayloadV1,2,3,4` with same base params as
`newPayloadV1,2,3,4` and one more additional param (`witness`) of type
`bytes`. The method returns `statelessPayloadStatusV1`, which mirrors
`payloadStatusV1` but replaces `latestValidHash` with `stateRoot` and
`receiptRoot`.
After this PR, https://github.com/ethereum/go-ethereum/pull/28187, the
way to set the default logger is different. This PR only updates the way
to set logger in some test cases' comments that existed in the codebase
(since this commit
https://github.com/ethereum/go-ethereum/commit/b63e3c37a6). Although I
am not sure if it a good way to leave the code in the comment, it truly
makes me more efficiently to debug and fix the failing test cases.
This change makes the code slightly easier for downstream-projects to extend with more signer-types, but if functionalily equivalent to the previous code.
This PR fixes what https://github.com/ethereum/go-ethereum/pull/30306/
broke. Escaping the `?` in the event sub query was fixed in that PR but
it was still escaped in the `updates` request. This PR adds a URL params
argument to `httpGet` and fixes `updates` query formatting.
Remove redundant address presence check in `makeGasSStoreFunc`.
This PR simplifies the `makeGasSStoreFunc` function by removing the
redundant check for address presence in the access list. The updated
code now only checks for slot presence, streamlining the logic and
eliminating unnecessary panic conditions.
This change removes the unnecessary address presence check, simplifying
the code and improving maintainability without affecting functionality.
The previous panic condition was intended as a canary during the testing
phases (i.e. _YOLOv2_) and is no longer needed.
h/t @MariusVanDerWijden for finding and fixing this on devnet 3.
I made the mistake of thinking `PayloadVersion` was correlated with the
`GetPayloadVX` method, but it actually tracks which version of
`PayloadAttributes` were passed to `forkchoiceUpdated`. So far, Prague
does not necessitate a new version of fcu, so there is no need for
`PayloadV4`.

This PR fixes an issue with blob transaction propagation due to the blob
transation txpool rejecting transactions with gapped nonces. The
specific changes are:
- fetch transactions from a peer in the order they were announced to
minimize nonce-gaps (which cause blob txs to be rejected
- don't wait on fetching blob transactions after announcement is
received, since they are not broadcast
Testing:
- unit tests updated to reflect that fetch order should always match tx
announcement order
- unit test added to confirm blob transactions are scheduled immediately
for fetching
- running the PR on an eth mainnet full node without incident so far

This is a successor PR to #25743. This PR is based on a new iteration of
the spec: https://github.com/ethereum/execution-apis/pull/484.
`eth_multicall` takes in a list of blocks, each optionally overriding
fields like number, timestamp, etc. of a base block. Each block can
include calls. At each block users can override the state. There are
extra features, such as:
- Include ether transfers as part of the logs
- Overriding precompile codes with evm bytecode
- Redirecting accounts to another address
## Breaking changes
This PR includes the following breaking changes:
- Block override fields of eth_call and debug_traceCall have had the
following fields renamed
- `coinbase` -> `feeRecipient`
- `random` -> `prevRandao`
- `baseFee` -> `baseFeePerGas`

This pull request replaces the field pointer in journal entry with the

While it will introduce the extra allocation cost, but it's easier for
code reading. Let's measure the overhead overall to see if the change is
acceptable or not.
This pull request introduces a state.Reader interface for state
accessing.
The interface could be implemented in various ways. It can be pure trie
only reader, or the combination of trie and state snapshot. What's more,
this interface allows us to have more flexibility in the future, e.g.
the
archive reader (for accessing archive state).
Additionally, this pull request removes the following metrics
- `chain/snapshot/account/reads`
- `chain/snapshot/storage/reads`
This PR fixes a flaky jwt-test.
The test is a jwt "from one second in the future". The test passes; the
reason for this is that the CI-system is slow, and by the time the jwt

future.

This PR changes how sidechains are handled.
Before the merge, it was possible to import a chain with lower td and not set it as canonical. After the merge, we expect every chain that we get via InsertChain to be canonical. Non-canonical blocks can still be inserted
with InsertBlockWIthoutSetHead.
If during the InsertChain, the existing chain is not canonical anymore, we mark it as a sidechain and send the SideChainEvents normally.
This pull request fixes a flaw in prefetcher.
In verkle tree world, both accounts and storage slots are committed into
a single tree instance for state hashing. If the prefetcher is activated, we will
try to pull the trie for the prefetcher for performance speedup.
However, we had a special logic to skip pulling storage trie if the
storage root is empty. While it's true for merkle as we have nothing to
do with an empty storage trie, it's totally wrong for verkle. The consequences
for skipping pulling is the storage changes are committed into trie A, while the
account changes are committed into trie B (pulled from the prefetcher), boom.
This PR adds the bulk verkle witness+proof production at the end of block
production. It reads all data from the tree in one swoop and produces
a verkle proof.

When attempting to hash a typed data struct that includes a type
reference with a fixed-size array, the validation process fails.
According to EIP-712, arrays can be either fixed-size or dynamic,
denoted by `Type[n]` or `Type[]` respectively, although it appears this
currently isn't supported.
This change modifies the validation logic to accommodate types
containing fixed-size arrays.
This is a follow-up to #29520, and a preparatory PR to a more thorough
change in the journalling system.
### API methods instead of `append` operations
This PR hides the journal-implementation details away, so that the
statedb invokes methods like `JournalCreate`, instead of explicitly
appending journal-events in a list. This means that it's up to the
journal whether to implement it as a sequence of events or
aggregate/merge events.
### Snapshot-management inside the journal
This PR also makes it so that management of valid snapshots is moved
inside the journal, exposed via the methods `Snapshot() int` and
`RevertToSnapshot(revid int, s *StateDB)`.
### SetCode
JournalSetCode journals the setting of code: it is implicit that the
previous values were "no code" and emptyCodeHash. Therefore, we can
simplify the setCode journal.
### Selfdestruct
The self-destruct journalling is a bit strange: we allow the
selfdestruct operation to be journalled several times. This makes it so
that we also are forced to store whether the account was already
destructed.
What we can do instead, is to only journal the first destruction, and
after that only journal balance-changes, but not journal the
selfdestruct itself.
This simplifies the journalling, so that internals about state
management does not leak into the journal-API.

Preimages were, for some reason, integrated into the journal management,

In few tests the returned error from `SendTransaction` is not being
checked. This PR checks the returned err in tests.
Returning errors also revealed tx in `TestCommitReturnValue` is not
actually being sent, and returns err ` only replay-protected (EIP-155)
transactions allowed over RPC`. Fixed the transaction by using the
`testTx` function.
`WriteToUDP` was never called, since `meteredUdpConn` exposed directly
all the methods from the underlying `UDPConn` interface.
This fixes the `discover/egress` metric never being updated.
This pull request adds a few more performance metrics, specifically:
- The average time cost of an account read
- The average time cost of a storage read
- The rate of account reads
- The rate of storage reads
This is a performance improvement on the account-creation rollback code
required for the archive node to support verkle. It uses the utility
function `DeleteAtStem` to remove code and account data per-group
instead of doing it leaf by leaf.
It also fixes an index bug, as code is chunked in 31-byte chunks, so
comparing with the code size should use 31 as its stride.

This PR adds the `dns:read` and `dns:edit` permissions to the required
set of permissions checked before deploying an ENR tree to Cloudflare.
These permissions are necessary for a successful publish.
**Background**:
The current logic for `devp2p dns to-cloudflare` checks for `zone:edit`
and `zone:read` permissions. However, when running the command with only
these two permissions, the following error occurs:
```
wrong permissions on zone REMOVED-ZONE: map[#zone:edit:false #zone:read:true]
```
Adding `zone:read` and `zone:edit` to the API token led to a different
error:
```
INFO [08-19|14:06:16.782] Retrieving existing TXT records on pos-nodes.hardfork.dev
Authentication error (10000)
```
This suggested that additional permissions were required. I added
`dns:read`, but encountered another error:
```
INFO [08-19|14:11:42.342] Retrieving existing TXT records on pos-nodes.hardfork.dev
INFO [08-19|14:11:42.851] Updating DNS entries
failed to publish REMOVED.pos-nodes.hardfork.dev: Authentication error (10000)
```
Finally, after adding both `dns:read` and `dns:edit` permissions, the
command executed successfully with the following output:
```
INFO [08-19|14:13:07.677] Checking Permissions on zone REMOVED-ZONE

```
With this PR, the required permissions for deploying an ENR tree to
Cloudflare now include `zone:read`, `zone:edit`, `dns:read`, and
`dns:edit`. The initial check now includes all of the necessary
permissions and indicates in the error message which permissions are
missing:
```

This PR updates the version of go used in builds and docker to
1.23.0. Release notes: https://go.dev/doc/go1.23
More importantly, following our policy of maintaining the last two
versions (which now becomes 1.23 and 1.22), we can now make use of
the things that were introduced in 1.22: https://go.dev/doc/go1.22
Go 1.22 makes two changes to “for” loops.
- each iteration creates new variables,
- for loops may range over integers
Other than that, some interesting library changes and other stuff.
This PR implements the conclusions from
https://github.com/ethereum/go-ethereum/issues/28987#issuecomment-2296075028,
that is:
Building with `--strip-all` as a ld-flag to the cgo linker, to remove
symbols. Without that, some spurious reference to a temporary file is
included into the kzg-related library.
Building with `--build-id=none`, to avoid putting a `build id` into the file.
closes#29475, replaces #29657, #30104
Fixes two issues. First is a deadlock where the txpool attempts to reorg, but can't complete because there are no readers left for the new txs subscription. Second, resolves a problem with on demand mode where txs may be left pending when there are more pending txs than block space.

Our `WriteArchive`, used by ci builder, creates files in the repo root,in order to upload. After we've built the amd64-builds, we create the uploads, and cause the repo to be flagged as dirty for the remaining builds.
This change fixes it by adding the artefacts to gitignore. Closes#30324
When we are building in detached head, we cannot easily obtain the same information as we can if we're in non-detached head.
However, one thing we _can_ obtain is the git-hash and git-date. Currently, we omit to include the git-date into the build-info, which causes problem for reproducable builds which are on a detached head.
This change fixes it to include the date-info always.
To allow all error paths in `vm.EVM.create()` to consume the necessary
gas, there is currently a pattern of gating code on `if err == nil`
instead of returning as soon as the error occurs. The same behaviour can
be achieved by abstracting the gated code into a method that returns
immediately on error, improving readability and thus making it easier to
understand and maintain.
Here I am adding a discv5 nodes source into the p2p dial iterator. It's
an improved version of #29533.
Unlike discv4, the discv5 random nodes iterator will always provide full
ENRs. This means we can apply filtering to the results and will only try
dialing nodes which explictly opt into the eth protocol with a matching
chain.
I have also removed the dial iterator from snap. We don't have an
official DNS list for snap anymore, and I doubt anyone else is running
one. While we could potentially filter for snap on discv5, there will be
very few nodes announcing it, and the extra iterator would just stall
the dialer.

Add coinbase address to javascript tracer context.
This PR adds the `coinbase` address to `jsTracer.ctx`, allowing access
to the coinbase address (fee receipient) in custom JavaScript tracers.
Example usage:
```javascript
result: function(ctx) {
return toAddress(ctx.coinbase);
}
```
This change enables custom tracers to access coinbase address,
previously unavailable, enhancing their capabilities to match built-in
tracers.
This pull request drops the legacy transaction retrieval support from before

This pull request fixes#30229.
During snap sync, large storage will be split into several pieces and
synchronized concurrently. Unfortunately, the tradeoff is that the respective
merkle trie of each storage chunk will be incomplete due to the incomplete
boundaries. The trie nodes on these boundaries will be discarded, and any
dangling nodes on disk will also be removed if they fall on these paths,
ensuring the state healer won't be blocked.
However, the dangling account trie nodes on the path from the root to the
associated account are left untouched. This means the dangling account trie
nodes could potentially stop the state healing and break the assumption that the
entire subtrie should exist if the subtrie root exists. We should consider the
account trie node as the ancestor of the corresponding storage trie node.
In the scenarios described in the above ticket, the state corruption could occur
if there is a dangling account trie node while some storage trie nodes are
removed due to synchronization redo.
The fixing idea is pretty straightforward, the trie nodes on the path from root
to account should all be explicitly removed if an incomplete storage trie
occurs. Therefore, a `delete` operation has been added into `gentrie` to
explicitly clear the account along with all nodes on this path. The special
thing is that it's a cross-trie clearing. In theory, there may be a dangling
node at any position on this account key and we have to clear all of them.
Fixes a slight miscalculation in the downloader queue, which was not accurately taking block withdrawals into account when calculating the size of the items in the queue

Some chains’ network IDs use hexadecimal such as Optimism ("0xa" instead
of "10"), so when converting the string to big.Int, we cannot specify
base 10; otherwise, it will encounter errors with hexadecimal network
IDs.
The struct-based tracing added in #29189 seems to have caused an issue
with the benchmark `BenchmarkTracerStepVsCallFrame`. On master we see
the following panic:
```console

The issue seems to be that `OnOpcode` expects that `OnTxStart` has
already been called to initialize the `env` value in the tracer. The JS
tracer uses it in `OnOpcode` for the `GetRefund()` method.
This patch resolves the issue by reusing the `Call` method already
defined in `runtime_test.go` which correctly calls `OnTxStart`.
Fixes#30254
It seems like the removed CreateAccount call is very old and not needed anymore.
After removing it, setting a sender that does not exist in the state doesn't seem to cause
an issue.
Adding the correct accessList parameter when calling a contract can
reduce gas consumption. However, the current version only allows adding
the accessList manually when constructing the transaction. This PR can
provide convenience for saving gas.

This PR fixes an issue in the setMode method of beaconBackfiller where the
log message was not displaying the previous mode correctly. The log message
now shows both the old and new sync modes.
## Issue
If `nextTime` has passed, but all nodes are excluded, `get` would return
`nil` and `run` would therefore not invoke `schedule`. Then, we schedule
a timer for the past, as neither `nextTime` value has been updated. This
creates a busy loop, as the timer immediately returns.
## Fix
With this PR, revalidation will be also rescheduled when all nodes are
excluded.

The test specifies `ListenAddr: ":0"`, which means a random ephemeral
port will be chosen for the TCP listener by the OS. Additionally, since
no `DiscAddr` was specified, the same port that is chosen automatically
by the OS will also be used for the UDP listener in the discovery UDP
setup. This sometimes leads to test failures if the TCP listener picks a
free TCP port that is already taken for UDP. By specifying `DiscAddr:
":0"`, the UDP port will be chosen independently from the TCP port,
fixing the random failure.
See issue #29830.
Verified using
```
cd p2p
go test -c -race
stress ./p2p.test -test.run=TestServerPortMapping
...
5m0s: 4556 runs so far, 0 failures
```
The issue described above can technically lead to sporadic failures on
systems that specify a listen address via the `--port` flag of 0 while
not setting `--discovery.port`. Since the default is using port `30303`
and using a random ephemeral port is likely not used much to begin with,
not addressing the root cause might be acceptable.
This pull request fixes the broken feature where the entire storage set is overridden.
Originally, the storage set override was achieved by marking the associated account
as deleted, preventing access to the storage slot on disk. However, since #29520, this
flag is also checked when accessing the account, rendering the account unreachable.
A fix has been applied in this pull request, which re-creates a new state object with all
account metadata inherited.
Currently, we have 3 flags to configure blob pool. However, we don't
read these flags and set the blob pool configuration in eth config
accordingly. This commit adds a function to check if these flags are
provided and set blob pool configuration based on them.
This pull request adds an additional error check after statedb.IntermediateRoot,
ensuring that no errors occur during this call. This step is essential, as the call might
encounter database errors.
The address recover is executed and cached in ValidateTransaction already. It's
expected that the cached one is returned in ValidateTransaction. However,
currently, we use the wrong function signer.Sender instead of types.Sender which
will do all the address recover again.
Here we add distinct error messages for network timeouts and JSON parsing errors.
Note this specifically applies to HTTP connections serving a single RPC request.

Originally, these metrics were added to track the largest storage wiping.
Since account self-destruction was deprecated with the Cancun fork,
these metrics have become meaningless.
This does not change the behavior here as the nonce in the argument is
tx.Nonce(). This commit helps to make the function easier to read and avoid
capturing the tx in the function.

enode.Node was recently changed to store a cache of endpoint information. The IP address in the cache is a netip.Addr. I chose that type over net.IP because it is just better. netip.Addr is meant to be used as a value type. Copying it does not allocate, it can be compared with ==, and can be used as a map key.
This PR changes most uses of Node.IP() into Node.IPAddr(), which returns the cached value directly without allocating.
While there are still some public APIs left where net.IP is used, I have converted all code used internally by p2p/discover to the new types. So this does change some public Go API, but hopefully not APIs any external code actually uses.
There weren't supposed to be any semantic differences resulting from this refactoring, however it does introduce one: In package p2p/netutil we treated the 0.0.0.0/8 network (addresses 0.x.y.z) as LAN, but netip.Addr.IsPrivate() doesn't. The treatment of this particular IP address range is controversial, with some software supporting it and others not. IANA lists it as special-purpose and invalid as a destination for a long time, so I don't know why I put it into the LAN list. It has now been marked as special in p2p/netutil as well.
This pull request fixes the pre-order trie traversal by defining
a more accurate iterator order and path comparison rule.

This should fix an occasional test failure in ethclient/simulated.TestForkResendTx.
Inspection of logs revealed the cause of the failure to be that the txpool was not done
reorganizing by the time Fork is called.
Here we clean up internal uses of type discover.node, converting most code to use
enode.Node instead. The discover.node type used to be the canonical representation of
network hosts before ENR was introduced. Most code worked with *node to avoid conversions
when interacting with Table methods. Since *node also contains internal state of Table and
is a mutable type, using *node outside of Table code is prone to data races. It's also
cleaner not having to wrap/unwrap *enode.Node all the time.
discover.node has been renamed to tableNode to clarify its purpose.
While here, we also change most uses of net.UDPAddr into netip.AddrPort. While this is
technically a separate refactoring from the *node -> *enode.Node change, it is more
convenient because *enode.Node handles IP addresses as netip.Addr. The switch to package
netip in discovery would've happened very soon anyway.
The change to netip.AddrPort stops at certain interface points. For example, since package
p2p/netutil has not been converted to use netip.Addr yet, we still have to convert to
net.IP/net.UDPAddr in a few places.
Create the directory before NewKeyStore. This ensures the watcher successfully starts on
the first attempt, and waitWatcherStart functions as intended.
It seems the semantic differences between addFoundNode and addInboundNode were lost in
#29572. My understanding is addFoundNode is for a node you have not contacted directly
(and are unsure if is available) whereas addInboundNode is for adding nodes that have
contacted the local node and we can verify they are active.
handleAddNode seems to be the consolidation of those two methods, yet it bumps the node in
the bucket (updating it's IP addr) even if the node was not an inbound. This PR fixes
this. It wasn't originally caught in tests like TestTable_addSeenNode because the
manipulation of the node object actually modified the node value used by the test.
New logic is added to reject non-inbound updates unless the sequence number of the
(signed) ENR increases. Inbound updates, which are published by the updated node itself,
are always accepted. If an inbound update changes the endpoint, the node will be
revalidated on an expedited schedule.

In #29572, I assumed the revalidation list that the node is contained in could only ever
be changed by the outcome of a revalidation request. But turns out that's not true: if the
node gets removed due to FINDNODE failure, it will also be removed from the list it is in.
This causes a crash.
The invariant is: while node is in table, it is always in exactly one of the two lists. So
it seems best to store a pointer to the current list within the node itself.
This pull request fixes the flay test TestSkeletonSyncRetrievals. In this test, we first
trigger a sync cycle and wait for it to meet certain expectations. We then inject a new
head and potentially also a new peer, then perform another final sync. The test now
performs the newPeer addition before launching the final sync, and waits a bit for that
peer to get registered. This fixes the logic race that made the test fail sometimes.

enode.Node has separate accessor functions for getting the IP, UDP port and TCP port.
These methods performed separate checks for attributes set in the ENR.
With this PR, the accessor methods will now return cached information, and the endpoint is
determined when the node is created. The logic to determine the preferred endpoint is now
more correct, and considers how 'global' each address is when both IPv4 and IPv6 addresses
are present in the ENR.
Node discovery periodically revalidates the nodes in its table by sending PING, checking
if they are still alive. I recently noticed some issues with the implementation of this
process, which can cause strange results such as nodes dropping unexpectedly, certain
nodes not getting revalidated often enough, and bad results being returned to incoming
FINDNODE queries.
In this change, the revalidation process is improved with the following logic:
- We maintain two 'revalidation lists' containing the table nodes, named 'fast' and 'slow'.
- The process chooses random nodes from each list on a randomized interval, the interval being
faster for the 'fast' list, and performs revalidation for the chosen node.
- Whenever a node is newly inserted into the table, it goes into the 'fast' list.
Once validation passes, it transfers to the 'slow' list. If a request fails, or the
node changes endpoint, it transfers back into 'fast'.
- livenessChecks is incremented by one for successful checks. Unlike the old implementation,
we will not drop the node on the first failing check. We instead quickly decay the
livenessChecks give it another chance.
- Order of nodes in bucket doesn't matter anymore.
I am also adding a debug API endpoint to dump the node table content.

Added a start/end system where tracer can be notified that processing of some Ethereum system calls is starting processing and also notifies it when the processing has completed.
Doing a start/end for system call will enable tracers to "route" incoming next tracing events to go to a separate bucket than other EVM calls. Those not interested by this fact can simply avoid registering the hooks.
The EVM call is going to be traced normally afterward between the signals provided by those 2 new hooks but outside of a transaction context OnTxStart/End. That something implementors of live tracers will need to be aware of (since only "trx tracers" are not concerned by ProcessBeaconRoot).

This PR fixes some flaws with the existing tests.
The randomized testing (TestSnapshotRandom) executes a series of steps which modify the state and create journal-events. Later on, we compare the forward-going-states against the backwards-unrolling-journal-states, and check that they are identical.
The "identical" check is performed using various accessors. It turned out that we failed to check some things:
- the accesslist contents
- the transient storage contents
- the 'newContract' flag
- the dirty storage map
This change adds these new checks
Currently our state journal tracks each storage update to a contract, having the ability to revert those changes to the previously set value.
For the very first modification however, it behaves a bit wonky. Reverting the update doesn't actually remove the dirty-ness of the slot, rather leaves it as "change this slot to it's original value". This can cause issues down the line with for example write witnesses needing to gather an unneeded proof.
This PR modifies the storageChange journal entry to not only track the previous value of a slot, but also whether there was any previous value at all set in the current execution context. In essence, the PR changes the semantic of storageChange so it does not simply track storage changes, rather it tracks dirty storage changes, an important distinction for being able to cleanly revert the journal item.
This change adds a testcase and fixes a corner-case in the skeleton sync.
With this change, when doing the skeleton cleanup, we check if the filled header is acually within the range of what we were meant to backfill. If not, it means the backfill was a noop (possibly because we started and stopped it so quickly that it didn't have time to do any meaningful work). In that case, just don't clean up anything.

The beacon root when applied in `state_processor.go` is performed right before executing transaction. That means that contract reliying on this value would query the same value found in the block header.
In that spirit, it means that any tracing/operation relying on state data which touches transaction must have updated the beacon root before any transaction processing.
This PR adds an extra mechanism to sync.HeadSync that tries to retrieve the latest finality update from every server each time it sends an optimistic update in a new epoch (unless we already have a validated finality update attested in the same epoch).
Note that this is not necessary and does not happen if the new finality update is delivered before the optimistic update. The spec only mandates light_client_finality_update events when a new epoch is finalized. If the chain does not finalize for a while then we might need an explicit request that returns a finality proof that proves the same finality epoch from the latest attested epoch.
This change fixes three flaky tests `TestEth2AssembleBlock`,`TestEth2NewBlock`, `TestEth2PrepareAndGetPayload` and `TestDisable`.

This change removes support for subscribing to pending logs.
"Pending logs" were always an odd feature, because it can never be fully reliable. When support for it was added many years ago, the intention was for this to be used by wallet apps to show the 'potential future token balance' of accounts, i.e. as a way of notifying the user of incoming transfers before they were mined. In order to generate the pending logs, the node must pick a subset of all public mempool transactions, execute them in the EVM, and then dispatch the resulting logs to API consumers.
This PR updates the bls contracts from our internal implementation which is an unmaintained fork of the kilic library to the gnark-crypto library that is actively maintained by consensys.
It also updates the gas-costs according to the EIP
This pull request defines a gentrie for snap sync purpose.
The stackTrie is used to generate the merkle tree nodes upon receiving a state batch. Several additional options have been added into stackTrie to handle incomplete states (either missing states before or after).
In this pull request, these options have been relocated from stackTrie to genTrie, which serves as a wrapper for stackTrie specifically for snap sync purposes.
Further, the logic for managing incomplete state has been enhanced in this change. Originally, there are two cases handled:
- boundary node filtering
- internal (covered by extension node) node clearing
This changes adds one more:
- Clearing leftover nodes on the boundaries.
This feature is necessary if there are leftover trie nodes in database, otherwise node inconsistency may break the state healing.
time.After is equivalent to NewTimer(d).C, and does not call Stop if the timer is no longer needed. This can cause memory leaks. This change changes many such occations to use NewTimer instead, and calling Stop once the timer is no longer needed.

This addresses an edge-case (detailed in the code comment) where the computation of the intermediate trie root would force the unnecessary resolution of a hash node. The change makes it so that when we process changes from a block, we first process trie-updates and afterwards process trie-deletions.
Before, `ToMessage` was returning both the resulting `Message` and an error while no error is returned now.
Those error checks were probably leftover from the past.
The StartHeadListener method will only be called once. So it can't just make one attempt
to connect to the eventsource endpoint, it has to keep trying. Note that once the stream
is established, the eventsource implementation itself will keep retrying.
Here we add a Go API for running tracing plugins within the main block import process.
As an advanced user of geth, you can now create a Go file in eth/tracers/live/, and within
that file register your custom tracer implementation. Then recompile geth and select your tracer
on the command line. Hooks defined in the tracer will run whenever a block is processed.
The hook system is defined in package core/tracing. It uses a struct with callbacks, instead of
requiring an interface, for several reasons:
- We plan to keep this API stable long-term. The core/tracing hook API does not depend on
on deep geth internals.
- There are a lot of hooks, and tracers will only need some of them. Using a struct allows you
to implement only the hooks you want to actually use.
All existing tracers in eth/tracers/native have been rewritten to use the new hook system.
This change breaks compatibility with the vm.EVMLogger interface that we used to have.
If you are a user of vm.EVMLogger, please migrate to core/tracing, and sorry for breaking
your stuff. But we just couldn't have both the old and new tracing APIs coexist in the EVM.

This pull request introduces a database tool for inspecting the state history.
It can be used for either account history or storage slot history, within a
specific block range.
The state output format can be chosen either with
- the "rlp-encoded" values (those inserted into the merkle trie)
- the "rlp-decoded" value (the raw state value)
The latter one needs --raw flag.
This adds support for the Deneb beacon chain fork, and fork handling

This changes makes it so that when `evm statetest` executes, regardless of whether `--json` is specified or not, the stateroot is printed on `stderr` as a `jsonl` line. This enables speedier execution of testcases in goevmlab, in cases where full execution op-by-op is not required.
Since Go 1.22 has deprecated certain elliptic curve operations, this PR removes

Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths.
Package path implements utility routines for manipulating slash-separated paths.
The path package should only be used for paths separated by forward slashes, such as the paths in URLs
Here we add a beacon chain light client for use by geth.
Geth can now be configured to run against a beacon chain API endpoint,
without pointing a CL to it. To set this up, use the `--beacon.api` flag. Information
provided by the beacon chain is verified, i.e. geth does not blindly trust the beacon
API endpoint in this mode. The root of trust are the beacon chain 'sync committees'.
The configured beacon API endpoint must provide light client data. At this time, only
Lodestar and Nimbus provide the necessary APIs.
There is also a standalone tool, cmd/blsync, which uses the beacon chain light client
to drive any EL implementation via its engine API.

As SELF-DESTRUCT opcode is disabled in the cancun fork(unless the
account is created within the same transaction, nothing to delete
in this case). The account will only be deleted in the following
cases:
- The account is created within the same transaction. In this case
the original storage was empty.
- The account is empty(zero nonce, zero balance, zero code) and
is touched within the transaction. Fortunately this kind of accounts
are not-existent on ethereum-mainnet.
All in all, after cancun, we are pretty sure there is no large contract
deletion and we don't need this mechanism for oom protection.
The prestateTracer was reporting an inaccurate nonce for the contract being created in
post EIP-158 transactions. Correct nonce is 0, due to the issue nonce was being reported as 1.

This PR enhances eth_createAccessList RPC call to support scenarios where the node is launched with an unlimited gas cap (--rpc.gascap 0). The eth_createAccessList RPC call returns failure if user doesn't explicitly set a gas limit.
eth_call and debug_traceCall allow users to override various block fields, among them base fee. However the overriden base fee was not considered for computing the effective gas price of that message, and instead base fee of the base block was used. This has been fixed in this commit.
This PR fixes an overflow which can could happen if inconsistent blockchain rules were configured. Additionally, it tries to prevent such inconsistencies from occurring by making sure that merge cannot be enabled unless previous fork(s) are also enabled.

This pull request fixes a flaw in ethstats which can lead to node crash
A panic could happens when the local blockchain is reorging which causes the original head block not to be reachable (since number->hash canonical mapping is deleted). In order to prevent the panic, the block nilness is now checked in ethstats.
Improving two things here:
On hive, where we look at these tests, the Go code comment above the test
is not visible. When there is a failure, it's not obvious what the test is actually
expecting. I have converted the comments in to printed log messages to
explain the test more.
Second, I noticed that besu is failing some tests because it happens to request
a header when we want it to send transactions. Trying the minimal fix here to
serve the headers.

At some point, `ForkchoiceUpdatedV2` stopped working for `PayloadAttributesV1` while `paris` was active. This was causing a few failures in hive. This PR fixes that, and also adds a gate in `ForkchoiceUpdatedV1` to disallow `PayloadAttributesV3`.
GetPayloadVX should only return payloads which match its version. GetPayloadV2 is a special snowflake that supports v1 and v2 payloads. This change uses a a version-specific prefix within in the payload id, basically a namespace for the version number.
This PR fixes an issues in the new simulated backend. The root cause is the fact that the transaction pool has an internal reset operation that runs on a background thread.
When a new transaction is added to the pool via the RPC, the transaction is added to a non-executable queue and will be moved to its final location on a background thread. If the machine is overloaded (or simply due to timing issues), it can happen that the simulated backend will try to produce the next block, whilst the pool has not yet marked the newly added transaction executable. This will cause the block to not contain the transaction. This is an issue because we want determinism from the simulator: add a tx, mine a block. It should be in there.
The PR fixes it by adding a Sync function to the txpool, which waits for the current reset operation (if any) to finish, and then runs an entire round of reset on top. The new round is needed because resets are only triggered by new head events, so newly added transactions will not trigger the outer resets that we can wait on. The transaction pool would eventually internally do a reset even on transaction addition, but there's no easy way to wait on that and there's no meaningful reason to bubble that across everything. A clean outer reset will at worse be a small noop goroutine.
This PR introduces a few changes with respect to payload verification in fcu and new payload requests:
* First of all, it undoes the `verifyPayloadAttributes(..)` simplification I attempted in #27872.
* Adds timestamp validation to fcu payload attributes [as required](https://github.com/ethereum/execution-apis/blob/main/src/engine/cancun.md#specification-1) (section 2) by the Engine API spec.
* For the new payload methods, I also update the verification of the executable data. For `newPayloadV2`, it does not currently ensure that cancun values are `nil`. Which could make it possible to submit cancun payloads through it.
* On `newPayloadV3` the same types of checks are added. All shanghai and cancun related fields in the executable data must be non-nil, with the addition that the timestamp is _only_ with cancun.
* Finally it updates a newly failing catalyst test to call the correct fcu and new payload methods depending on the fork.
This change switches from using the `Hasher` interface to add/query the bloomfilter to implementing it as methods.
This significantly reduces the allocations for Search and Rebloom.
This change makes use of uin256 to represent balance in state. It touches primarily upon statedb, stateobject and state processing, trying to avoid changes in transaction pools, core types, rpc and tracers.
This change simplifies the logic for indexing transactions and enhances the UX when transaction is not found by returning more information to users.
Transaction indexing is now considered as a part of the initial sync, and `eth.syncing` will thus be `true` if transaction indexing is not yet finished. API consumers can use the syncing status to determine if the node is ready to serve users.
The code to compute a versioned hash was duplicated a couple times, and also had a small
issue: if we ever change params.BlobTxHashVersion, it will most likely also cause changes
to the actual hash computation. So it's a bit useless to have this constant in params.
EIP-4844 adds a new transaction type for blobs. Users can submit such transactions via `eth_sendRawTransaction`. In this PR we refrain from adding support to `eth_sendTransaction` and in fact it will fail if the user passes in a blob hash.
However since the chain can handle such transactions it makes sense to allow simulating them. E.g. an L2 operator should be able to simulate submitting a rollup blob and updating the L2 state. Most methods that take in a transaction object should recognize blobs. The change boils down to adding `blobVersionedHashes` and `maxFeePerBlobGas` to `TransactionArgs`. In summary:
- `eth_sendTransaction`: will fail for blob txes
- `eth_signTransaction`: will fail for blob txes
The methods that sign txes does not, as of this PR, add support the for new EIP-4844 transaction types. Resuming the summary:
- `eth_sendRawTransaction`: can send blob txes
- `eth_fillTransaction`: will fill in a blob tx. Note: here we simply fill in normal transaction fields + possibly `maxFeePerBlobGas` when blobs are present. One can imagine a more elaborate set-up where users can submit blobs themselves and we fill in proofs and commitments and such. Left for future PRs if desired.
- `eth_call`: can simulate blob messages
- `eth_estimateGas`: blobs have no effect here. They have a separate unit of gas which is not tunable in the transaction.
In the tracing tests, the base fee was generally set to nil. This commit changes this to pass the proper base instead, and fixes the few tests which become broken by the change.
Given the discussions around deprecating pending (see #28623 or ethereum/execution-apis#495), we can move away from using the pending block internally, and use latest instead
* accounts, ethclient: minor tweaks on the new simulated backend
* ethclient/simulated: add an initial batch of gas options
* accounts, ethclient: remove mandatory gasLimit constructor param
* accounts, ethclient: minor option naming tweaks
This is a rewrite of the 'simulated backend', an implementation of the ethclient interfaces
which is backed by a simulated blockchain. It was getting annoying to maintain the old
version of the simulated backend feature because there was a lot of code duplication with
the main client.
The new version is built using parts that we already have: an in-memory geth node instance
running in developer mode provides the chain, while the Go API is provided by ethclient.
A backwards-compatibility wrapper is provided, but the simulated backend has also moved to
a more sensible import path: github.com/ethereum/go-ethereum/ethclient/simulated

When managing geth, it is sometimes desirable to do a partial wipe; deleting state but retaining freezer data. A partial wipe can be somewhat tricky to accomplish.
This change implements the ability to perform partial wipe by making it possible to run geth removedb non-interactive, using command line options instead.
This pull request improves the condition to check if path state scheme is in use.
Originally, root node presence was used as the indicator if path scheme is used or not. However due to fact that root node will be deleted during the initial snap sync, this condition is no longer useful.
If PersistentStateID is present, it shows that we've already configured for path scheme.
Original problem was caused by #28595, where we made it so that as soon as we start to sync, the root of the disk layer is deleted. That is not wrong per se, but another part of the code uses the "presence of the root" as an init-check for the pathdb. And, since the init-check now failed, the code tried to re-initialize it which failed since a sync was already ongoing.
The total impact being: after a state-sync has begun, if the node for some reason is is shut down, it will refuse to start up again, with the error message: `Fatal: Failed to register the Ethereum service: waiting for sync.`.
This change also modifies how `geth removedb` works, so that the user is prompted for two things: `state data` and `ancient chain`. The former includes both the chaindb aswell as any state history stored in ancients.

This change fixes a problem with our non-core binaries: evm, clef, bootnode.
First of all, they failed to convert from legacy loglevels 1 to 5, to the new slog loglevels -4 to 4.
Secondly, the logging was actually setup in the init phase, and then overridden in the main. This is not needed for evm, since it used the same flag name as the main geth verbosity. Better to let the flags/internal handle the logging init.
Certain flags, such as `--rpc.txfeecap` currently do not have an env-var auto-generated for them. This change adds three missing cli flag types to the auto env-var helper function to fix this.

This fixes a database corruption issue that could occur during state healing.
When sync is aborted while certain modifications were already committed, and a
reorg occurs, the database would contain incorrect trie nodes stored by path.
These nodes need to detected/deleted in order to obtain a complete and fully correct state
after state healing.

This change implements CommitteeChain which is a key component of the beacon light client. It is a passive data structure that can validate, hold and update a chain of beacon light sync committees and updates, starting from a checkpoint that proves the starting committee through a beacon block hash, header and corresponding state. Once synced to the current sync period, CommitteeChain can also validate signed beacon headers.
The dump after state-test didn't work, the problem was an error, "Already committed", which was silently ignored.
This change re-initialises the state, so the dumping works again.
This change
- Removes interface `log.Format`,
- Removes method `log.FormatFunc`,
- unexports `TerminalHandler.TerminalFormat` formatting methods (renamed to `TerminalHandler.format`)
- removes the notion of `log.Lazy` values
The lazy handler was useful in the old log package, since it
could defer the evaluation of costly attributes until later in the
log pipeline: thus, if the logging was done at 'Trace', we could
skip evaluation if logging only was set to 'Info'.
With the move to slog, this way of deferring evaluation is no longer
needed, since slog introduced 'Enabled': the caller can thus do
the evaluate-or-not decision at the callsite, which is much more
straight-forward than dealing with lazy reflect-based evaluation.
Also, lazy evaluation would not work with 'native' slog, as in, these
two statements would be evaluated differently:
```golang
log.Info("foo", "my lazy", lazyObj)
slog.Info("foo", "my lazy", lazyObj)
```
These changes improves the performance of the non-coloured terminal formatting, _quite a lot_.
```
name old time/op new time/op delta
TerminalHandler-8 10.2µs ±15% 5.4µs ± 9% -47.02% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta
TerminalHandler-8 2.17kB ± 0% 0.40kB ± 0% -81.46% (p=0.008 n=5+5)
name old allocs/op new allocs/op delta
TerminalHandler-8 33.0 ± 0% 5.0 ± 0% -84.85% (p=0.008 n=5+5)
```
I tried to _somewhat_ organize the commits, but the it might still be a bit chaotic. Some core insights:
- The function `terminalHandler.Handl` uses a mutex, and writes all output immediately to 'upstream'. Thus, it can reuse a scratch-buffer every time.
- This buffer can be propagated internally, making all the internal formatters either write directly to it,
- OR, make use of the `tmp := buf.AvailableBuffer()` in some cases, where a byte buffer "extra capacity" can be temporarily used.
- The `slog` package uses `Attr` by value. It makes sense to minimize operating on them, since iterating / collecting into a new slice, iterating again etc causes copy-on-heap. Better to operate on them only once.
- If we want to do padding, it's better to copy from a constant `space`-buffer than to invoke `bytes.Repeat` every single time.
Add read locking of db lock around access to dirties cache in hashdb.Database to prevent
data race versus hashdb.Database.dereference which can modify the dirities map by deleting

This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21.
Main changes are as follows:
* removes any log handlers that were unused in the Geth codebase.
* Json, logfmt, and terminal formatters are now slog handlers.
* Verbosity level constants are changed to match slog constant values. Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options.
* `--log.backtraceat` and `--log.debug` are removed.
The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged.
A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed.
----
For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did
```golang
log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true))))
```
You now instead need to do
```golang
log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true)))

This change fixes two type-inconsistencies in the JS tracer:
- In most places we return byte arrays as a `Uint8Array` to the tracer. However it seems we missed doing the conversion for `ctx` fields which are passed to the tracer during `result`. They are passed as simple arrays. I think Uint8Arrays are more suitable and we should change this inconsistency. Note: this will be a breaking-change. But I believe the effect is small. If we look at our tracers we see that these fields (`ctx.from`, `ctx.to`, etc.) are used in 2 ways. Passed to `toHex` which takes both array or buffer. Or the length was measured which is the same for both types.
- The `slice` taking in `int, int` params versus `memory.slice` taking `int64, int64` params. I suggest changing `slice` types to `int64`. This should have no effect almost in any case.
There were several problems related to dumping state.
- If a preimage was missing, even if we had set the `OnlyWithAddresses` to `false`, to export them anyway, the way the mapping was constructed (using `common.Address` as key) made the entries get lost anyway. Concerns both state- and blockchain tests.
- Blockchain test execution was not configured to store preimages.
This changes makes it so that the block test executor takes a callback, just like the state test executor already does. This callback can be used to examine the post-execution state, e.g. to aid debugging of test failures.
* cmd, les, tests: remove light client code
This commit removes the light client (LES) code.

it is hard to maintain it alongside the normal client.

maybe rework and reintroduce it in the future.

* cmd: re-add flags and mark as deprecated
* cmd: warn the user about deprecated flags
* eth: better error message
Adds a subcommand: `geth snapshot export-preimages`, to export preimages of every hash found during a snapshot enumeration: that is, it exports _only the active state_, and not _all_ preimages that have been used but are no longer part of the state.
This tool is needed for the verkle transition, in order to distribute the preimages needed for the conversion. Since only the 'active' preimages are exported, the output is shrunk from ~70GB to ~4GB.
The order of the output is the order used by the snapshot enumeration, which avoids database thrashing. However, it also means that storage-slot preimages are not deduplicated.
geth --dev can be used with an existing data directory and genesis block. Since
dev mode only works with PoS, we need to verify that the merge has happened.

This PR moves our fuzzers from tests/fuzzers into whatever their respective 'native' package is.
The historical reason why they were placed in an external location, is that when they were based on go-fuzz, they could not be "hidden" via the _test.go prefix. So in order to shove them away from the go-ethereum "production code", they were put aside.
But now we've rewritten them to be based on golang testing, and thus can be brought back. I've left (in tests/) the ones that are not production (bls128381), require non-standard imports (secp requires btcec, bn256 requires gnark/google/cloudflare deps).
This PR also adds a fuzzer for precompiled contracts, because why not.
This PR utilizes a newly rewritten replacement for go-118-fuzz-build, namely gofuzz-shim, which utilises the inputs from the fuzzing engine better.
This change allows the creation of a genesis block for verkle testnets. This makes for a chunk of code that is easier to review and still touches many discussion points.
Currently, geth's will return `[]` for any `len(topics) > 4` log filter. The EVM only supports up to four logs, via LOG4 opcode, so larger criterias fail. This change makes the filter query exit early in those cases.
cockroachdb/pebble@422dce9 added Errorf to the Logger interface, this change makes it possible to compile geth with that version of pebble by adding the corresponding method to panicLogger.
* cmd/geth: more testcases for logging
This adds more edgecases around logging, particularly around handling of different types of nil-values

but not actively used by any testcase at the moment.

Currently, one can use the "withLogs" parameter to include logs in the
callTracer results, which allows the user to see at which trace level
was each log emitted.
This commit adds a position field to the logs which determine
the exact ordering of a call's logs and its subcalls. This would
be useful e.g. for explorers wishing to display the flow of execution.

This change improves GenerateChain to support internal chain history access (ChainReader)
for the consensus engine and EVM.
GenerateChain takes a `parent` block and the number of blocks to create. With my changes,
the consensus engine and EVM can now access blocks from `parent` up to the block currently
being generated. This is required to make the BLOCKHASH instruction work, and also needed
to create real clique chains. Clique uses chain history to figure out if the current signer is in-turn,
for example.
I've also added some more accessors to BlockGen. These are helpful when creating transactions:
- g.Signer returns a signer instance for the current block
- g.Difficulty returns the current block difficulty
- g.Gas returns the remaining gas amount
Another fix in this commit concerns the receipts returned by GenerateChain. The receipts now
have properly derived fields (BlockHash, etc.) and should generally match what would be
returned by the RPC API.
This adds warning logs when the read does not match the expected count.
We can also remove the size limit since the function documentation explicitly states
that callers should limit the count.

This PR is a bit in preparation for the slog work in #28187 .
Our current test re logging mostly test the internals, but we have no real end-to-end test of the logging output. This PR introduces a simple reexec-based log tester. This also relies upon a special mode in geth, which can be made to eject a set of predefined log messages (only available if the build-tag `integrationtests` is used
e.g. go run --tags=integrationtests ./cmd/geth --log.format terminal logtest
While working on this, I also noticed a quirk in the setup: when geth was configured to use a file output, then two separate handlers were used (one handler for the file, one handler for the console). Using two separate handlers means that two formatters are used, thus the formatting of any/all records happened twice. This PR changes the mechanism to use two separate io.Writers instead, which is both more optimal and fixes a bug which occurs due to a global statefulness in the formatter.
The String() version of BlockNumberOrHash uses decimal for all block numbers, including negative ones used to indicate labels. Switch to using BlockNumber.String() which encodes it correctly for use in the JSON-RPC API.
This PR removes panics from stacktrie (mostly), and makes the Update return errors instead. While adding tests for this, I also found that one case of possible corruption was not caught, which is now fixed.
This change closes https://github.com/ethereum/go-ethereum/issues/27730 . By using an iterator instead of a slice of transactions, we can better handle the case when an individual transaction (within an otherwise well-formed RLP-list) cannot be decoded.
Fixes a bug where the ethstats omits to report full block contents. This bug was a side-effect of https://github.com/ethereum/go-ethereum/pull/26777, where `CurrentBlock` was changed to return a header instead of a block, leading to a failed type assertion.
A goroutine is used to manage the lifetime of subscriptions managed by
resubscriptions. When the subscription ends with no error, the resub
goroutine ends as well. However, the resub goroutine needs to live
long enough to read from the unsub channel. Otheriwse, an Unsubscribe
call deadlocks when writing to the unsub channel.
This is fixed by adding a buffer to the unsub channel.

This change fixes#28355, where eth_getProof failed to return the correct codehash under certain conditions. This PR changes the logic to unconditionally look up the codehash, and also adds some more tests.
During snap-sync, we request ranges of values: either a range of accounts or a range of storage values. For any large trie, e.g. the main account trie or a large storage trie, we cannot fetch everything at once.
Short version; we split it up and request in multiple stages. To do so, we use an origin field, to say "Give me all storage key/values where key > 0x20000000000000000". When the server fulfils this, the server provides the first key after origin, let's say 0x2e030000000000000 -- never providing the exact origin. However, the client-side needs to be able to verify that the 0x2e03.. indeed is the first one after 0x2000.., and therefore the attached proof concerns the origin, not the first key.
So, short-short version: the left-hand side of the proof relates to the origin, and is free-standing from the first leaf.
On the other hand, (pun intended), the right-hand side, there's no such 'gap' between "along what path does the proof walk" and the last provided leaf. The proof must prove the last element (unless there are no elements).
Therefore, we can simplify the semantics for trie.VerifyRangeProof by removing an argument. This doesn't make much difference in practice, but makes it so that we can remove some tests. The reason I am raising this is that the upcoming stacktrie-based verifier does not support such fancy features as standalone right-hand borders.

This change addresses an issue in snap sync, specifically when the entire sync process can be halted due to an encountered empty storage range.
Currently, on the snap sync client side, the response to an empty (partial) storage range is discarded as a non-delivery. However, this response can be a valid response, when the particular range requested does not contain any slots.
For instance, consider a large contract where the entire key space is divided into 16 chunks, and there are no available slots in the last chunk [0xf] -> [end]. When the node receives a request for this particular range, the response includes:
The proof with origin [0xf]
A nil storage slot set
If we simply discard this response, the finalization of the last range will be skipped, halting the entire sync process indefinitely. The test case TestSyncWithUnevenStorage can reproduce the scenario described above.
In addition, this change also defines the common variables MaxAddress and MaxHash.

- Removes the owner-notion from a stacktrie; the owner is only ever needed for comitting to the database, but the commit-function, the `writeFn` is provided by the caller, so the caller can just set the owner into the `writeFn` instead of having it passed through the stacktrie.
- Removes the `encoding.BinaryMarshaler`/`encoding.BinaryUnmarshaler` interface from stacktrie. We're not using it, and it is doubtful whether anyone downstream is either.

When MatcherSession encounters an error, it attempts to close the session.
Closing waits for all goroutines to finish, including the 'distributor'. However, the
distributor will not exit until all requests have returned.
This patch fixes the issue by delivering the (empty) result to the distributor

This fixes some issues with flags in cmd/evm. The supported flags did not

* rlp/rlpgen: remove build tag
This tag was supposed to prevent unstable output when types reference each other. Imagine
there are two struct types A and B, where a reference to type B is in A. If I run rlpgen
on type B first, and then on type A, the generator will see the B.EncodeRLP method and
call it. However, if I run rlpgen on type A first, it will inline the encoding of B.
The solution I chose for the initial release of rlpgen was to just ignore methods
generated by rlpgen using a build tag. But there is a problem with this: if any code in
the package calls EncodeRLP explicitly, the package can't be loaded without errors anymore
in rlpgen, because the loader ignores it. Would be nice if there was a way to just make it
ignore invalid functions during type checking (they're not necessary for rlpgen), but
golang.org/x/tools/go/packages does not provide a way of ignoring them.
Luckily, the types we use rlpgen with do not reference each other right now, so we can
just remove the build tags for now.
This adds block and receipt fields for EIP-4844.

This change includes a lot of things, listed below.
### Split up interfaces, write vs read
The interfaces have been split up into one write-interface and one read-interface, with `Snapshot` being the gateway from write to read. This simplifies the semantics _a lot_.
Example of splitting up an interface into one readonly 'snapshot' part, and one updatable writeonly part:
```golang
type MeterSnapshot interface {
Count() int64
Rate1() float64
Rate5() float64
Rate15() float64
RateMean() float64
}
// Meters count events to produce exponentially-weighted moving average rates
// at one-, five-, and fifteen-minutes and a mean rate.
type Meter interface {
Mark(int64)
Snapshot() MeterSnapshot
Stop()
}
```
### A note about concurrency
This PR makes the concurrency model clearer. We have actual meters and snapshot of meters. The `meter` is the thing which can be accessed from the registry, and updates can be made to it.
- For all `meters`, (`Gauge`, `Timer` etc), it is assumed that they are accessed by different threads, making updates. Therefore, all `meters` update-methods (`Inc`, `Add`, `Update`, `Clear` etc) need to be concurrency-safe.
- All `meters` have a `Snapshot()` method. This method is _usually_ called from one thread, a backend-exporter. But it's fully possible to have several exporters simultaneously: therefore this method should also be concurrency-safe.
TLDR: `meter`s are accessible via registry, all their methods must be concurrency-safe.
For all `Snapshot`s, it is assumed that an individual exporter-thread has obtained a `meter` from the registry, and called the `Snapshot` method to obtain a readonly snapshot. This snapshot is _not_ guaranteed to be concurrency-safe. There's no need for a snapshot to be concurrency-safe, since exporters should not share snapshots.
Note, though: that by happenstance a lot of the snapshots _are_ concurrency-safe, being unmutable minimal representations of a value. Only the more complex ones are _not_ threadsafe, those that lazily calculate things like `Variance()`, `Mean()`.
Example of how a background exporter typically works, obtaining the snapshot and sequentially accessing the non-threadsafe methods in it:
```golang
ms := metric.Snapshot()
...
fields := map[string]interface{}{
"count": ms.Count(),
"max": ms.Max(),
"mean": ms.Mean(),
"min": ms.Min(),
"stddev": ms.StdDev(),
"variance": ms.Variance(),
```
TLDR: `snapshots` are not guaranteed to be concurrency-safe (but often are).
### Sample changes
I also changed the `Sample` type: previously, it iterated the samples fully every time `Mean()`,`Sum()`, `Min()` or `Max()` was invoked. Since we now have readonly base data, we can just iterate it once, in the constructor, and set all four values at once.
The same thing has been done for runtimehistogram.
### ResettingTimer API
Back when ResettingTImer was implemented, as part of https://github.com/ethereum/go-ethereum/pull/15910, Anton implemented a `Percentiles` on the new type. However, the method did not conform to the other existing types which also had a `Percentiles`.
1. The existing ones, on input, took `0.5` to mean `50%`. Anton used `50` to mean `50%`.
2. The existing ones returned `float64` outputs, thus interpolating between values. A value-set of `0, 10`, at `50%` would return `5`, whereas Anton's would return either `0` or `10`.
This PR removes the 'new' version, and uses only the 'legacy' percentiles, also for the ResettingTimer type.
The resetting timer snapshot was also defined so that it would expose the internal values. This has been removed, and getters for `Max, Min, Mean` have been added instead.
### Unexport types
A lot of types were exported, but do not need to be. This PR unexports quite a lot of them.
This updates minisign to the latest version. One new thing is that minisign (not go-minisign) has started to prehash the file, and in order to make geth pass the version-check, we need to sign the file in legacy-mode.
On ACD 163, it was agreed to bump the target and max blob values from `2/4` to `3/6` for future devnets until we could decide on final mainnet number. This change contains said update, making master pass all the hive tests. The final decision for mainnet cancun is still to be made.

This changes implements faster post-selfdestruct iteration of storage slots for deletion, by using snapshot-storage+stacktrie to recover the trienodes to be deleted. This mechanism is only implemented for path-based schema.
For hash-based schema, the entire post-selfdestruct storage iteration is skipped, with this change, since hash-based does not actually perform deletion anyway.

This PR makes EIP-4788 work in the engine API and miner. It also fixes some bugs related to
EIP-4844 block processing and mining. Changes in detail:
- Header.BeaconRoot has been renamed to ParentBeaconRoot.
- The engine API now implements forkchoiceUpdatedV3
- newPayloadV3 method has been updated with the parentBeaconBlockRoot parameter
- beacon root is now applied to new blocks in miner
- For EIP-4844, block creation now updates the blobGasUsed field of the header
Just some minor optimizations I figured out a while ago. By using ReadBytes instead of
Bytes on the rlp stream, we can save the allocation of a temporary buffer for the typed tx
payload.
If kind == rlp.Byte, the size reported by Stream.Kind will be zero, but we need a buffer
of size 1 for ReadBytes. Since typed txs always have to be longer than 1 byte, we can just
return an error for kind == rlp.Byte.
There is a also a small change for Log: since the first three fields of Log are the ones that
should appear in the canon encoding, we can simply ignore the remaining fields via
struct tag. Doing this removes an indirection through the rlpLog type.

The PR #26274 broke the evm statetest command a bit, in that it stopped spitting out the stateroot following a non-successful statetest-execution.
This PR changes it back, so the stateroot is unconditionally output on stderr, and makes it so fuzzing works again.
This change implements "EIP 4788 : Beacon block root in the EVM". It implements version-2 of EPI-4788, main difference being that the contract is an actual contract rather than a precompile, as in #27289.
Currently, we trigger the logic to (un)index transactions when the node receives a new
block. However, in some cases the node may not receive new blocks (eg, when the Geth node
is configured without peer discovery, or when it acts as an RPC node for historical-only
data).
In these situations, the Geth node user may not have previously configured txlookuplimit
(i.e. the default of around one year), but later realizes they need to index all
historical blocks. However, adding txlookuplimit=0 and restarting geth has no effect. This
change makes it check for required indexing work once, on startup, to fix the issue.

Optimizations:
- Previously, if a transaction was reverting, EstimateGas would exhibit worst-case behavior and binary search up to the max gas limit (~40 state-clone + tx executions). This change allows EstimateGas to return after only a single unconstrained execution in this scenario.
- Uses the gas used from the unconstrained execution to bias the remaining binary search towards the likely solution in a simple way that doesn't impact the worst case. For a typical contract-invoking transaction, this reduces the median number of state-clone+executions from 25 to 18 (28% reduction).
Cleanup:
- added & improved function + code comments
- correct the EstimateGas documentation to clarify the gas limit determination is at latest block, not pending, if the blockNr is unspecified.
ReadSkeletonHeader can return nil if the header is missing, so we should
not access fields on it. Note that calling .Hash() on a nil header is fine, so there
is no need to actually check for nil.

This changes the forkID calculation to ignore time-based forks that occurred before the
genesis block. It's supposed to be done this way because the spec says:
> If a chain is configured to start with a non-Frontier ruleset already in its genesis, that is NOT considered a fork.
This raises the JSON-RPC batch request limits significantly for the engine API endpoint.
The limits are now also hard-coded, so users won't get them wrong. I have chosen these limits:
maximum batch items: 2000
maximum batch response size: 250MB
While it would also be possible to disable batch limits completely for the engine API,
I think having some limits is a good safety net against misbehaving CLs. Since this
isn't configurable, we really want to ensure this limit will never become an issue in the
CL/EL communication, so I set them quite high.

This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way
of keeping the blob sidecar within types.Transaction. It's better this way because most
code in go-ethereum does not care about blob transactions, and probably never will. This
will start mattering especially on the client side of RPC, where all APIs are based on
types.Transaction. Users need to be able to use the same signing flows they already
have.
However, since blobs are only allowed in some places but not others, we will now need to
add checks to avoid creating invalid blocks. I'm still trying to figure out the best place
to do some of these. The way I have it currently is as follows:
- In block validation (import), txs are verified not to have a blob sidecar.
- In miner, we strip off the sidecar when committing the transaction into the block.
- In TxPool validation, txs must have a sidecar to be added into the blobpool.
- Note there is a special case here: when transactions are re-added because of a chain
reorg, we cannot use the transactions gathered from the old chain blocks as-is,
because they will be missing their blobs. This was previously handled by storing the
blobs into the 'blobpool limbo'. The code has now changed to store the full
transaction in the limbo instead, but it might be confusing for code readers why we're
not simply adding the types.Transaction we already have.
Code changes summary:
- txpool.Transaction removed and all uses replaced by types.Transaction again
- blobpool now stores types.Transaction instead of defining its own blobTx format for storage
- the blobpool limbo now stores types.Transaction instead of storing only the blobs
- checks to validate the presence/absence of the blob sidecar added in certain critical places
The Go authors updated golang/x/ext to change the function signature of the slices sort method.
It's an entire shitshow now because x/ext is not tagged, so everyone's codebase just

This PR updates the dep on our code too and does all the refactorings to follow upstream...
This should fix#27726. With enough load, it might happen that the SetPongHandler
callback gets invoked before the call to SetReadDeadline is made in pingLoop. When
this occurs, the socket will end up with a 30s read deadline even though it got the pong,
which will lead to a timeout.
The fix here is processing the pong on pingLoop, synchronizing with the code that
sends the ping.
Block takes a number and a hash. The spec is unclear on what should happen in this case, leaving it an implemenation detail. With this change, we return an error in case both number and hash are passed in.
This change removes a chainconfig parameter passed into rawdb.ReadLogs, which is not used nor needed.
It also modifies the filter loop slightly, avoiding a labeled break and instead using a method.
This change does not modify any behaviour.

Maintaining your own private network is more involved as a lot of configurations taken for

#### Defining the private genesis state
Unfortunately since [the Merge](https://ethereum.org/en/roadmap/merge/) it is no longer possible
to easily set up a network of geth nodes without also setting up a corresponding beacon chain.
First, you'll need to create the genesis state of your networks, which all nodes need to be
aware of and agree upon. This consists of a small JSON file (e.g. call it `genesis.json`):
There are three different solutions depending on your use case:
